DOOR STOP AND HOLDER.

Application filed August 17, 1925. Serial No. 50,811.

My invention relates to an improvement in door stops and holders, and has for its object the provision of a superior device of the class described for holding a door in its open position.

In the accompanying drawings:

Fig. 1 is a broken top or plan view of a door stop and holder constructed in accordance with my invention;

Fig. 2 is a broken side view thereof;

Fig. 3 is a view thereof in end elevation looking toward its outer end;

Fig. 4 is a similar view but looking toward its inner end; 7 Y

Fig. 5 is a broken top or plan view of my improved fixture as mounted upon a door which is shown in its closed position;

Fig. 6 is a corresponding view but showing the door in its open position; and

Fig. 7 is a vertical sectional view on the line A.B of Fig. 2.

In carrying out my invention as herein shown, I employ a channel-shaped brace member 8 receiving at its outer end a rivet 10, by means of which it is secured to the horizontal arm of an L-shaped bracket 9, which is provided with screw-holes to adapt it to be secured to the inner face of a door 25, as shown in Figs. 5 and 6. Interposed between the brace 8 and the bracket 9 is a spacing or bearing-washer 22. Near its inner end the brace 8 is provided with a vertical aperture 11, the forward wall of which is adapted to co-act with a pawl 4, which is hung upon a horizontal pin 6 extending between the two depending arms of a U-shaped yoke 2, which latter, in turn, is pivoted by means of a rivet 23 to a plate 1, from which it is spaced by a bearing-washer 3. The plate 1 just mentioned is provided with screw-holes, as shown, to adapt it to be secured to the underface of the upper doorframe, as shown in Fig. 2. The brace 8 is adapted to pass between the depending arms of the U-shaped yoke 2 and is guided therein by a roller 5 mounted upon a transverse pin .7 extending between the said arms.

The pawl 4 aforesaid is adapted to enter the aperture 11 in the brace 8 when the latter reaches the limit of its outward movement, as a result of opening the door 25 to which it is attached, with the result that by co-acting with the forward wall of the said aperture it will prevent the inward movement of the brass and hence maintain the door in its open To disengage the pawl 4 from the aperture 11, I provide a bell-crank lever 14, which 1 is mounted in the rear end of the said brace by means of a transverse pin 12, upon which it rocks. At the 111110131011 of its two arms,

the bell-crank lever 14 is provided with two stop lugs 16, the upper one of which co-acts with the rear Wall of the aperture 11 to limit the upward swing of the releasing arm 18 of the lever 14, while the lower lug co-acts with the underface of the brace to limit the rocking movement of the lever in the opposite direction. A spring 17,coupled at its upper end to the rear end of the'brace 8 and at its lower end to the lever 14, serves to maintain the arm 18 in its lowermost posiion, in which it will not interfere with the entry of the pawl 4 into the aperture 11.

To provide for retiring the pawl 4 from the aperture 11 so as to permit the brace 8 to slide inward, as required, to close the door, h 1

I connect to the lower end of thebell-crank lever 14 a chain 13 which extends outward over a roller 15 and depends therefrom in a convenient position near the center of the door, where it is provided at its extreme lower end with a pull-ring 20. The roller 15 just above described is mounted in a U- shaped bracket 19 secured to the underface of the brace 8, from it depends by means of a rivet 24.

In the operation of my improved door stop and holder, the door is swung open from the position in which it is shown in Fig. 5 to the position in which it is shown in Fig. 6, with the result that the brace 8 slides outward over the roller 5 and between the depending arms of the pivotal yoke 2 until the pin 12, upon which the bell-crank lever 14 is mounted, engages the rear edges of the said yoke, which serves to check the outward swing of the door. W henthe brace has been moved to this position, the aperture 11 is brought into registration with the pawl 4, so that the same drops therein and efiectively prevents the door from being swung into its closed position by engaging the forward wall of the said aperture. l/Vhen it is desired to close the door, it is, of course, necessary to swing the pawl 4 out of the aperture 11, which may be accomplished by downward pull upon the outer end of the chain 13, which will, in turn, rock the bell-crank lever 14 upon its pin 12 and 7 cause the arm 18 of the said lever ts swing upward and correspondingly the pawl 4. The brace 8 is now free to slide inward through the yoke 2 to permit the door to be closed. r

I claim:' V

l. A door holder comprising a plate with suitable means for fastening same to door jamb, a yoke swivelly connected to said plate, a awl pivotally assembled between the two cownwardly projecting ears of the yoke, a brace pivotally connected to a door bracket or hinge slidably connected to said swivel yoke, resting on yoke roll, an aperture in brace to properly register with pawl, a trigger suitably mounted in brace and to register with pawl when brace is in locked position, means to rock trigger so as to disengage pawl from aperture in brace.

2. A door holder comprising a plate with suitable means for fastening same to door jamb or casing, a yoke swivelly connected to said plate, a pawl pivotally assembled .between the two downwardly-prejecting ears of yoke, a roller mounted on a pin between downward projecting ears of yoke.

3. A door holder, comprising a reciprocating'brace;a pivot-fixture secured to one end thereof; a pawl-engaging abutment located near the opposite end of the said brace; a guide-fixture for the said brace adapted to be secured to a door-frame; a pawl mounted in the said guide-fixture for 'co-action with the aforesaid abutment; a

lever carried by the said brace for disengaging the pawl from the said abutment; and a pull-chain or cord for operatingwthe said lever.

4. A door holder, comprising a reciproeating brace; a pivot-fixture secured to one end thereof; a pawl-receiving passage formed in the opposite end of the said brace; a guide-fixture for the said brace, adapted to be secured to a door-frame; a pawl carried by the said guide-fixture for entry into the aforesaid passage and co-action with the forward wall thereof; a lever carried by the said brace in a position to engage the said pawl for retiring it from the said passage;

and a pull-chain or cord for operating the said lever.

5. A door holder, comprising a recipro eating brace; a pivot-fixture and an idlerpulley secured to one end thereof; a pawlengaging abutment located near the opposite end of the said brace; a guide-fixture for the said brace adapted to be secured to a doorframe; a pawl carried by the said guide-fixture for co-action with the aforesaid abutment; a lever carried by the said brace for disengaging the pawl from the said abutment; and a pull-chain or cord passing over the aforesaid idler-pulley and connected to the said lever for operating the same.
